I installed 2008 as a separate installation along with mycurrentversion 2007. I restarted my computer after installation andduringthe windows startup my primary monitor stops anddisplays"signal error" (I use a dual monitors). I can onlyassumethis has something to do with the Solidworks installationbecauseit has been working fine for 6 months now and onlyhappeneddirectly after installing SW 2008. I've restarted and stillhavethe same problem as well as un installing 2008 and still havethesame problem. I've checked display drivers& displaysettings. I've tried switching the plugs of bothmonitors into thegraphics card and the only config that willdisplay is my secondarymonitor being plugged into the secondarygraphics card slot.SolidworksAdministration
